Mariah Carey’s husband Nick Cannon has quit his daily radio show on doctor’s orders after he was hospitalized for the fourth time in three months last week. The America’s Got Talent presenter was recently diagnosed with acute kidney failure after falling ill while on a post-Christmas family vacation in Aspen, Colorado. He subsequently underwent surgery in Los Angeles and returned for further treatment in January.

He was back under doctors’ care last Friday when he was diagnosed with blood clots in his lungs and an enlarged ventricle in his heart.

Cannon addressed his health woes on air, revealing his physician has urged him to cut back on work, adding, “My doctor was saying that my work is going to kill me – and he’s not joking. I think part of the reason why my health did kind of deteriorate was because I wasn’t resting a lot and I was doing too much. I was overworking myself, working out too much.”

Now he’s heeded the doctor’s warning and will step down from his morning show on New York’s WXRK station.

A statement from Cannon reads, “Under doctor’s orders, I have been asked to cut back on some of my professional commitments to allow my body to get the rest it needs to keep up with the demands of my multitasking schedule. Even Superman has to sleep.”

He will continue to host syndicated radio show Cannon’s Countdown and America’s Got Talent.
